Certain vehicles will receive a software update to add to the existing Check Engine Light a Driver Information Center (DIC) warning message if DTC P0016 sets. Dealers will reprogram the Engine Control Module (ECM).

About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
